You want everything the engine produces translated to those big slicks right now, not when the engine hits max RPM. Older drag racing transmissions were a combination of two- and four-speed manuals.
As drag racers, we build our engines to produce the maximum horsepower and torque early in the torque band and then drop off pretty quickly. Back when I was turning times at the track, we were using rear-ends with 4. Another reason was that there too much torque lost in the torque converter.
However, companies like ATI have automatics out like the SuperGlide4 mentioned above that can handle almost 4, horsepower and that have some extra-awesome gear ratios for us drag racers. These companies have also created the lock-up converter. This is a torque converter that starts transferring full engine torque through the transmission at much lower engine RPMs than standard torque converters. Thus, we get a better launch. This is one of the main advantages of an automatic transmission.
You can either let it shift itself, bump shift with your knee, or use paddle shifters on the steering wheel. Another reason you might choose a manual over an automatic also deals with ease of shifting. Straight cut gears are essential for racing vehicles because they produce no axial load and increase torque, which allows the car to perform more efficiently. Because the axial load is decreased by the straight cut gears, it is easier for drivers to shift gears without having to use the clutch pedal.
Due to the fact that straight cut gears mesh together all at once, a shrill noise is produced in the transmission that can be heard while watching NASCAR races.
NASCAR transmission development is heavily regulated to create an equal playing field for the drivers. No parts of the transmission may be modified without prior approval from the governing body. Reports indicate that NASCAR's next-generation stock car features a six-speed gearbox, as opposed to the four-speed gearboxes currently used. NASCAR has relied on the four-speed H-pattern gearbox since the sport's inception in , so the upgrade to a sequential six-speed transmission in is significant.
Some automatic drivers even wish they are skilled in driving a manual. Every time you move, you also have to move your shift and press the clutch, brakes, and accelerator. More work but less distance covered. A manual transmission is much more complicated and will require more time to learn. One of the things that people wish is when a car rolls back. You can get rid of it, however, once you finally buy an automatic vehicle.
You will notice most of the time that the top specked cars always have an automatic transmission. Usually, the common car types offer such.
As a result, many people just simply refer to it as automatic. Manual transmissions have fewer selections compared to the automatic ones. Simply because automatic transmissions are very popular. With all the quirks that an automatic has, it kind of becomes understandable.
Automatic has better features and looks. There are usually two people that buy a manual these days: people that are on a budget or specialists who love cars or races with manual transmission for a living. All brands offer an automatic; therefore, if you prefer the automatic, you will have more selections… not to mention top trims are mostly offered in automatic.
The market is already in your favor. In other words, if you want to impress a girl with your driving skills, driving an automatic will probably work for you. It all equates to better launch, faster start and efficient driving experience.
One of the popular and most efficient automatic transmissions today is the CVT that is used by various car manufacturers. Automatic transmission will require less shifting. It can be a good thing in the sense that they are still able to do other stuff while driving like calling people and doing a meeting in that setup. They will still be able to focus on the road. Meanwhile, some people prefer automatics because of its ease of use and its simplicity.
For the people that want to have both worlds, you can have automatic transmissions that can also go on manual mode. The recent Suzuki Spresso and the Mazda 3 are good examples of that. Automatic cars are way more expensive than manual cars because the latter has special tools and systems, which make it function as an automatic. Adding to the price are the higher trim levels, which are only offered exclusively in automatic.
You should know that owning an automatic is also costly as far as maintenance and repair is concerned. Automatic cars have more moving parts, which means they need extra special care. An automatic transmission also aims to simplify the driving experience. The cost of that? More parts to add to the engine itself to make it move forward all the time.
Subjectively, people hate automatic cars because they are not that fun to drive. Besides, there are automatic transmissions as mentioned above that offer a manual option.
